Empeleni, ubuchwepheshe be-COB, njengoba busetshenziswa kuma-LCD, bubandakanya ukunamathiselwa okuqondile kwesekethe ehlanganisiwe (IC) elawula ukusebenza kwesibonisi ebhodini lesekethe eliphrintiwe (PCB), elibese lixhunywa kuphaneli ye-LCD ngokwayo. Lokhu kuhluke kakhulu nezindlela zokupakisha ezivamile, ezivame ukudinga amabhodi omshayeli angaphandle amakhulu, anzima kakhulu. Ubuhlakani be-COB bulele ekhonweni layo lokuhlela kahle umhlangano, ikhuthaze imojuli yokubonisa ehlangene futhi eqinile. I-silicon die engenalutho, wona kanye ubuchopho besibonisi, buboshelwe ngokucophelela ku-PCB, bese imbozwa ngenhlaka evikelayo. Lokhu kuhlanganiswa okuqondile akugcini nje ngokugcina izakhiwo ezibalulekile zendawo kodwa futhi kuqinisa ukuxhumana kukagesi, okuholela ekuthembekeni okuthuthukisiwe nokuhlala isikhathi eside kokusebenza.
Izinzuzo ezinikezwe ama-COB LCDs zinezici eziningi futhi ziyaphoqa. Okokuqala, yaboukwethembeka okuthuthukisiwekuwumphumela oqondile womklamo ohlanganisiwe. Ngokunciphisa izingxenye ezihlukene kanye nezintambo zangaphandle, amathuba okuba nokwehluleka kokuxhumeka anciphe kakhulu. Lokhu kuqina okungokwemvelo kwenza ama-COB LCDs afanelekele izinhlelo zokusebenza ezifuna ukusebenza okungantengantengi ezindaweni eziyinselele, njengamaphaneli amathuluzi ezimoto noma amasistimu okulawula izimboni aqinile. Okunamathiselwe okuqondile kunciphisa ubuthakathaka obuvame ukuhlotshaniswa nokuxhumana okuningi, kunikeza isisombululo sokubonisa esingamelana nokudlidliza okukhulu kanye nezingcindezi ezishisayo.
Okwesibili,ukusebenza kahle kwesikhalakuwuphawu lobuchwepheshe be-COB. Esikhathini lapho izinto zikagesi zincipha ngokuqhubekayo, yonke imilimitha iyigugu. Ama-LCD we-COB, anezinyathelo zawo ezinciphile, avumela ukwakhiwa kwemikhiqizo emincane, elula ngaphandle kokuyekethisa ukusebenza. Lokhu kubumbana kwenza inqubo yokuhlanganisa ibe lula, kube nomthelela ekwehliseni ubunzima bokukhiqiza futhi, ngokwengeza, izindleko zokukhiqiza. Ukuhlanganiswa kukhulula abaklami emikhawulweni yamamojula avamile amaningi, kuvula imibono emisha yokuklama komkhiqizo nokuphatheka. Isibonelo, i-Malio, ehamba phambili ekuboniseni izixazululo, inikeza aCOB LCD Module(P/N MLCG-2164). Le mojula ethile iyisibonelo sezimfanelo zokonga isikhala ze-COB, ihlinzeka ngendawo yokubuka enolwazi olunzulu ngaphakathi kwesici sefomu elisebenzayo, elifanele uhla olubanzi lwezinhlelo zokusebenza ezidinga kokubili amakhono ezithombe kanye nezinhlamvu.
Ngaphezu kwalokho, ama-COB LCDs ayaphawulekaukusebenza kahle kwamandla. Ukucushwa kwe-chip okuthuthukisiwe kanye nokunciphisa ukumelana kukagesi okuhambisana nomklamo wawo kunomthelela ekusetshenzisweni kwamandla okuphansi, into ebalulekile yamadivayisi asebenza ngebhethri namasistimu alwela ukusebenza ngendlela eqhubekayo. Ukuphatha okushisayo okusebenzayo kungenye inzuzo yangaphakathi.

Ngisho nasemishinini yezimboni, lapho imibukiso ibekezelela izimo zokusebenza ezinzima, ama-COB LCDs ahlinzeka ngempendulo ebonakalayo ethembekile.
I-COB iqhudelana ne-COG: Ukuhlangana Kwefilosofi Yokuklama
Ukuqonda okuncane kobuchwepheshe bokubonisa kuvame ukudinga ukudweba umehluko phakathi kwezindlela ezibonakala zifana. Enkulumweni yokuhlanganiswa kombukiso, ama-acronyms amabili avame ukuvela: COB (Chip-on-Board) kanyeI-COG (Chip-on-Glass). Nakuba bobabili behlose ukwenza kube mncane futhi kuthuthukise ukusebenza kwesibonisi, ukwehlukana kwabo okuyisisekelo kwezakhiwo kuholela ezinzuzweni ezihlukile nezinhlelo zokusebenza ezikhethwayo.
Umehluko oyisisekelo ulele ku-substrate lapho umshayeli i-IC ebekwe khona. Njengoba sekucacisiwe, ubuchwepheshe be-COB bunamathisela i-IC ngqo ku-PCB, bese ihlangana ne-LCD. Ngokuphambene, ubuchwepheshe be-COG budlula i-PCB yendabuko ngokuphelele, bukhweza i-IC yomshayeli ngqo ku-substrate yengilazi yephaneli ye-LCD. Lokhu kubophezela okuqondile kwe-IC engilazini kuphumela kumojuli ecwebezelayo futhi ecwebezelayo, okwenza i-COG ibe inketho ebaluleke kakhulu kumadivayisi lapho ukuzaca okudlulele nesisindo esincane kubaluleke kakhulu, njengama-smartphone, amawashi ahlakaniphile, namanye amagajethi kagesi aphathwayo.
Ngokombono wedizayini nosayizi, ama-COG LCDs ngokwemvelo anephrofayela encane ngenxa yokungabikho kwe-PCB ehlukile. Lokhu kuhlanganiswa okuqondile kuqondisa ukujula kwemojuli, kusize imiklamo emincane kakhulu yomkhiqizo. I-COB, nakuba isahlangene ngokuphawulekayo uma iqhathaniswa nobuchwepheshe obudala, igcina ukuguquguquka okuhlinzekwa yi-PCB, okuvumela izakhiwo eziyinkimbinkimbi nezenziwe ngezifiso. Lokhu kungase kuhlanganise ukufaka izingxenye ezengeziwe noma ukujikeleza okuyinkimbinkimbi ngokuqondile ebhodini, okungaba inzuzo ezinhlelweni ezithile ezidinga ukuhlakanipha okukhulu kwe-onboard noma ukuhlanganiswa kwe-peripheral.
Mayelana nokusebenza nokuqina, kokubili ubuchwepheshe bunikeza ukwethembeka okuphezulu. Kodwa-ke, ama-COG LCDs, ngenxa yokuba nezindawo ezimbalwa zokuxhuma (i-IC ngqo engilazini), ngezinye izikhathi ingaveza umkhawulo wokuqina ngokumelene nezinhlobo ezithile zokucindezeleka komshini. Ngokuphambene, ama-COB LCDs, ane-IC egxunyekwe ngokuvikelekile ku-PCB ezinzile futhi yambozwa, ivame ukunikeza inkundla eqine kakhulu yokusebenza kohlelo lonke, ikakhulukazi lapho ukumelana nokudlidliza noma umthelela kuwukukhathazeka okuyinhloko. Isici sokulungiseka futhi siyahlukana; kuyilapho amamojula e-COG aziwa njengenselele yokulungisa ngenxa yokuhlangana okuqondile engilazini, amamojula we-COB, ne-IC yawo ku-PCB ehlukile, anganikeza izindlela zokulungisa nokuguqula kalula.
Ukucatshangelwa kwezindleko nakho kuveza i-dichotomy. Ngokukhiqizwa kwevolumu ephezulu kakhulu yamamojula amisiwe, ubuchwepheshe be-COG bungabonakala bubiza kakhulu ngenxa yezinqubo zokuhlanganisa ezenziwe lula kanye nokuncipha kokusetshenziswa kwezinto ngokuhamba kwesikhathi. Kodwa-ke, ezinhlelweni ezidinga ukwenziwa ngokwezifiso okukhethekile noma ukugijima kwevolumu ephansi, ubuchwepheshe be-COB buvame ukunikeza ukusebenza kahle kwezomnotho, njengoba izindleko zamathuluzi zokubumba ingilazi ye-COG ngokwezifiso zinganqanda. Ubuchwepheshe bukaMalio budlulela kuI-LCD/LCM Segment Displays for Metering, enikeza inqwaba yezinketho zokwenza ngokwezifiso okuhlanganisa uhlobo lwe-LCD, umbala wangemuva, imodi yokubonisa, nebanga lokushisa elisebenzayo. Lokhu kuvumelana nezimo ekuhlanganiseni izixazululo zokubonisa kukhuluma nokuzivumelanisa nezimo kwemvelo kobuchwepheshe obufana ne-COB ekuhlangabezaneni nezimfuneko ze-bespoke, lapho ikhono lokushintsha idizayini ye-PCB libaluleke kakhulu.
Ukukhetha phakathi kwe-COB ne-COG ekugcineni kuncike ezimeni ezithile zohlelo lokusebenza. Ngemiklamo ebeka phambili ukuzaca kokugcina kanye nama-electronics evolumu aphezulu, i-COG ivamise ukuthatha indawo yokuqala. Nokho, izinhlelo zokusebenza ezifuna ukusebenza okuqinile okuqinile, ukuguquguquka kwedizayini, kanye nokuhambisana nozibuthe kagesi okuphakeme kakhulu, i-COB isalokhu iyinketho ephoqayo. Ikhono layo lokusekela ukujikeleza okuyinkimbinkimbi ku-PCB ehlanganisiwe kuyenza ibaluleke kakhulu ezimbonini, ezezimoto, nezinsimbi eziyisipesheli.
I-trajectory Yekusasa Yezibonisi Ezididiyelwe
Ukuvela kobuchwepheshe bokuboniswa wukufuna okuqhubekayo kokuxazulula okukhulu, ukucaca okuthuthukisiwe, nezici zefomu ezincishisiwe. Ubuchwepheshe be-COB LCD, nezinzuzo zabo zangaphakathi, bukulungele ukuhlala bungumdlali obalulekile kulokhu kuqhubekela phambili okuqhubekayo. Ukuthuthuka okuqhubekayo ezintweni ezihlanganisayo, amasu okubopha, kanye ne-IC miniaturization kuzoqhubeza nokucolisa amamojula we-COB, kuphushe imingcele yalokho okungenzeka ekuhlanganiseni kwesibonisi.
Ikhono lokupakisha izinto eziminyene, okuholela ekubonisweni kwe-"ultra-micro pitch", lizoveza izikrini ezinobuhlakani obungenakuqhathaniswa obubonakalayo kanye nokungabi namthungo. Lokhu kuminyana kuphinde kunikele ezilinganisoni eziphakeme zokungafani, njengoba ukungabikho kwezinto ezijwayelekile zokupakisha kunciphisa ukuvuza kokukhanya futhi kuthuthukisa ukujula kokumnyama. Ngaphezu kwalokho, ukuqina kwemvelo kanye nokuphathwa okushisayo okusebenzayo kwezakhiwo ze-COB kubenza babe abantu abafanelekile bezinhlelo zokusebenza eziboniswayo ezivelayo, okuhlanganisa nezibonisi eziguqukayo nezibonisa ngale, lapho izindlela zendabuko zilwela ukuhlangabezana nezidingo zomzimba.
I-Malio, ngokuzibophezela kwayo ekuboniseni izixazululo ezisezingeni eliphezulu, ihlale ihlola lezi ntuthuko. Izinhlobonhlobo zabo zemikhiqizo ye-COB, kusukela kumamojula wesithombe anokulungiswa okuphezulu kuya ekubonisweni kwezingxenye ezikhethekile zezinsimbi eziyinkimbinkimbi, kugcizelela ubuchwepheshe babo ekusebenziseni amandla aphelele alobu buchwepheshe. Ikusasa ngokungangabazeki lizofakaza ama-COB LCDs ehamba phambili emiklamo emisha yomkhiqizo, esiza indawo yokubuka egxilile, ehlala isikhathi eside, futhi eyonga amandla kuzo zonke izimboni.
